9 Claims.

This. invention relates to a combined ventilator and light.

.tilator.

Another object of the invention is to provide a novel air impeller for a ventilating device.

Another object of. the invention is to provide a ventilator including a, housinghaving a port therein with the closure for the port and wherein novel means is provided for operating the closure.

A further object of the invention is to provide a novel ventilator including a housing having a motor driven air impeller therein and wherein the housing is provided with a closure member which is moved to open position by operation of the motor.

Other objects and the advantages of my invention will be apparent from the accompanying description taken in connection with the accompanying drawings, wherein:

Fig. 1 is a central sectional view with parts in elevation showing my invention;

Fig. 2 is a sectional view on a reduced scale taken on line 2-2, Figure 1;

Figs. 3 and 4 are views similar to Fig. 2 taken on lines 33 and 4-4, respectively, Fig. l; and

Fig. 5 is'a central sectional view with parts in elevation showing a modification. Referring tothe drawings by reference characters, I have shown my invention as embodied in a combined light and ventilator which is indicated generally at H]. As shown the device includes a cylindrical housing II having a bottom closure I2 which may be welded thereto as at I3.

The housing has a flange IBa-thereon which fits in a hole I3b in a ceiling, I30 and is held in place by screw I3d. v

The closure I2 is provided with a plurality of apertures I4 through which air may pass into the housing. Arranged within the apertures I4 the closure I2 includes a depressed portion I5 forming a recess I6. In this recess I6 I arrange a boss II on the stator I8 of an electric motor. The top of the motor stator includes a boss I9 which is arranged in a recess 20 in a partition wardly as shown in dotted lines in Fig. 1. When moved downwardly (as shown in solid lines in Fig. l) by engagement with the motor it serves to clamp the motor in place.

Arranged upon the closure I2 I show a valve member 24 which has a central aperture 25 which receives the hub II. The valve member 24 includes apertures 26 which in one position of the valvemember are aligned with the apertures I4 in the closure I2 and in another position are disposed between the apertures I4 so that passages for air are provided. g

The closure I2 includes a pin 21 (see Fig. 1) which is upwardly directed and is arranged in an arcuate notch 28 in the valve 24. A spring 29 has one end attached at 30 to the valve 24 and at the other end to a post 3I on the wall of the housing II. The spring normally tends to urge the closure 24 to closed position.

The motor stator I8 has a depending pin'32 thereon which fits in a recess 33 on a socket member 34 arranged in the closure 24. The construction is such that when the motor-stator I8 is rotated it will cause the valve 24 to rotate with the housing thus moving the valve against the tension of the spring 29 and aligning the ports I4 and 26. This occurs when the motor has started. When the motor ceases operation the spring 25 will rotate the member 24 and the motor to close the ports.

The motor includes an armature shaft or rotor 40 on which a housing AI is secured by means of a screw 42. The housing 4| includes a flange 43 which engages a disc 44. The disc 44 has a central aperture 45 through which the armature shaft 40 extends.

Arranged upon the disc 44 I show a depending skirt 46 which has a plurality of spaced vanes 41 struck therefrom and bent inwardly. The vanes 41 are inclined in one direction and serve as impellers so that air is forced outwardly by the vanes 41. The skirt 46 has an outwardly extending flange 48 secured to the bottom thereof. This flange 48 is arranged close to the partition 2| so that there is practically no'passage for air between the flange 48 and the partition 2 I.

Upon the flange 43 I arrange an upwardly directed collar 49 which terminates adjacentto, but is spaced outwardly from, the disc 44. The partition 2| includes air passages 5|] with arms 5| therebetween.

In operation, when the motor rotor 40 is operated by leads 52 and 53 the disc 44 will be rotated, thus rotating the vanes 41 and drawing air through the ports l4 and 26 and through the apertures 50 whence the air passesthrough the vanes 41 and thence outwardly from the space 55 between the collar 49 and the vanes 41.

This occurs when the motor is operating and at the start of the operation of the motor the stator will turn slightly causing the parts l4 and 26 to be aligned. When the motor ceases to operate the spring 29 will cause the valve 24 to move to closed position.

The bottom closure l2 has a depending sleeve 60 thereon. This sleeve 60 has an internal flange Bl which is spot welded as at 62 to the closure l2. The sleeve 60 has an internal flange 63 thereon which supports a porcelain lamp socket supporting member 64. The supporting member 64 includes a lamp socket 65 from which a lamp 6E depends. Suitable leads 6'! and 68 supply current to the lamp. The sleeve 60 is provided with a plurality of spaced screws 10 which engage a shade H and hold the latter about the lamp 66.

In Fig. I show a modification of my invention wherein similar parts are designated by similarly primed reference numerals. In the modification the housing ll motor stator l8, etc. are similar to those previously described. The armature shaft or rotor 40 of the motor, instead of having an impeller thereon, as shown in Fig. 1, is provided with an impeller 80 which is of the usual bladed type and includes a hub 8| held in place on the armature shaft 40 by a set screw 82.
